Hi Anders,

I just noticed that Ruby mode can go into infinite recursion (or "Lisp
nesting exceeds ‘max-lisp-eval-depth’"). I managed to boil it down to
the following:
Evaluate (setq debug-on-error t)
Open a new file, say test.rb
Type:
func do {
And press return.
In the backtrace, the following is listed over and over again:
ruby-smie--indent-to-stmt()
ruby-smie-rules(:before "{")
smie-indent--rule-1(:before "{" nil nil)
smie-indent--rule(:before "{")
smie-indent-keyword()
run-hook-with-args-until-success(smie-indent-keyword)
smie-indent-calculate()
smie-indent-virtual()
It happens in Emacs 25.2 and in a week-old build from the master branch.
Sorry about the long wait, it didn't seem like a critical issue given
that the code in question was either a typo, or a very weird way to
write a block. Please correct me if I'm wrong here.
Either way, it should be fixed now in master, commit 0f561ee553.
